Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To detect the residual quantity of viscous fluid by providing detection means for detecting the residual quantity of viscous fluid in a tank by judging a load state in a movement from a current value of a driving motor measured by a current measuring section for measuring the current value of the driving motor. SOLUTION: A viscous fluid coater is provided with a vertical driving motor 21 for vertically reciprocating a viscous fluid coating unit 20, and a rotational driving motor 22 for rotating the viscous fluid coating unit 20. The vertical driving motor 21 is provided with a current measuring section 23. As the number of times for adhesive coating increases, the adhesive in the tank is reduced and the weight of the entire viscous fluid coating unit 20 is reduced. Therefore, the load in the vertical reciprocal movement is reduced and the current value of the vertical driving motor 21 is also reduced. Thus, the current value of the vertical driving motor 21 is measured by the current measuring section 23.  A detection control means is provided for setting a specified current value in advance and for raising an alarm if the measured current value is equal to or lower than the specified current value, thus enabling detection of the residual quantity of the viscous fluid.
